A head-mounted device may have a display for displaying image content. Head-mounted support structures in the device may be used to support the display. The head-mounted device or external equipment may include a three-dimensional image sensor. The three-dimensional image sensor may capture a three-dimensional image of a user's face. Control circuitry may analyze the three-dimensional image to identify which of multiple versions of a customizing face-fit module should be used in the electronic device to fit the device to the user's face. An appropriate face-fit module may be identified based on facial features such as facial size and the shapes of a user's forehead, nose, and cheeks. After identifying which version of the face-fit module is to be used by the user, that version of the face-fit module may be coupled to a non-custom portion of a main unit for the head-mounted device using magnets or other coupling structures.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An electronic device, comprising: a display that displays content for a user; control circuitry; head-mounted support structures that support the display and the control circuitry; and a three-dimensional image sensor that is supported by the head-mounted support structures and that captures a three-dimensional image of the user, wherein the head-mounted support structures include a first portion and a removable second portion, wherein the first portion supports the display, wherein the control circuitry is configured to analyze the three-dimensional image to identify a version of the second portion to couple to the first portion, and wherein the identified version of the second portion is removably coupled to the first portion and is configured to rest against the user while the display displays the content for the user.
2. The electronic device defined in claim 1 further comprising: lenses that are supported in the first portion; and actuators coupled to the lenses, wherein the three-dimensional image sensor comprises a forward-facing three-dimensional image sensor that faces away from the user while the user views the content and wherein the control circuitry uses the actuators to adjust the lenses based on the three-dimensional image of the user.
3. The electronic device defined in claim 1 further comprising magnetic structures configured to removably couple the second portion to the first portion.
4. The electronic device defined in claim 3 further comprising lenses that are supported in the first portion.
5. The electronic device defined in claim 4 wherein the control circuitry is configured to analyze the three-dimensional image to measure an interpupillary distance of the user and wherein the electronic device further comprises actuators in the first portion that move the lenses based on the measured interpupillary distance.
6. The electronic device defined in claim 5 further comprising a gaze tracking system, wherein the actuators move the lenses based on information from the gaze tracking system.
7. The electronic device define in claim 1 further comprising: an additional display on an exterior surface of the first portion, wherein the control circuitry is configured to display information on the identified version of the second portion on the additional display.
8. The electronic device defined in claim 1 wherein the second portion is a version of a face-fit module that is identified from among multiple versions of the face-fit module based on the three-dimensional image.
9. A system, comprising: a head-mounted support structure having a display and having a removable module configured to be worn against a face of a user while the user views content on the display; a three-dimensional image sensor that captures a three-dimensional image of the face of the user; and control circuitry configured to analyze the three-dimensional image to identify a version of the removable module to couple to head-mounted support structure from among multiple versions of the removable module, wherein the three-dimensional image sensor is coupled to the head-mounted support structure and captures the three-dimensional image of the face of the user while the head-mounted support structure is not being worn by the user.
10. The system defined in claim 9 wherein the head-mounted support structure has a non-custom portion that is coupled to the removable module, wherein the display comprises a rear-facing display on the non-custom portion that faces the user while the user views content on the display, and wherein the three-dimensional image sensor comprises a front-facing three-dimensional image sensor that faces away from the rear-facing display.
11. A head-mounted device, comprising: a strap; a main unit coupled to the strap, wherein the main unit includes a first portion and a second portion that is removably coupled to the first portion; a display in the first portion; a three-dimensional image sensor in the first portion; and control circuitry configured to analyze a three-dimensional image of a user's face that is captured with the three-dimensional image sensor to identify a version of the second portion to removably couple to the first portion to form the main unit.
12. The head-mounted device defined in claim 1 further comprising lenses, wherein the display comprises a rear-facing display that faces the user's face as the user is viewing content on the rear-facing display through the lenses.
13. The head-mounted device defined in claim 12 wherein the three-dimensional image sensor is on a front face of the main unit and faces away from the rear-facing display.
14. The head-mounted device defined in claim 13 further comprising an additional display on which information on the identified version of the second portion is displayed.
15. The head-mounted device defined in claim 14 wherein the main unit is configured to be worn against the user's face, wherein the first portion comprises a non-custom portion of the main unit with a front surface that faces away from the user's face when the main unit is being worn against the user's face and wherein the additional display and the three-dimensional image sensor are on the front surface.
16. The head-mounted device defined in claim 11 further comprising a first magnetic structure in the first portion and a corresponding second magnetic structure in the second portion, wherein the first and second magnetic structures removably couple the second portion to the first portion.
17. The head-mounted device defined in claim 11 further comprising actuators and lenses, wherein the control circuitry is configured to use the actuators to move the lenses based on analyzing the three-dimensional image.
18. The head-mounted device defined in claim 11 further comprising a gaze tracking system that monitors the user's eyes to determine an interpupillary distance, wherein the control circuitry is configured to move the lenses with the actuators using the interpupillary distance.
19. The head-mounted device defined in claim 11 wherein the three-dimensional image sensor captures the three-dimensional image of the face of the user while the head-mounted support structure is not being worn by the user.
